Only for the, well, I'm going to upset folk here. Folk that will accept bleeding edge issues. If you went with multi monitor at least we know you can get 1080p results. Maybe soon.
I'd hit tomshardware forums to ask this one. But when I need to compare GPUs I use GPUBOSS.com
Hello guys!
I want to setup some really performance focused gaming PC. Cash is not an issue – just want it to work better.
First of all, it must be AMD GPU. Yep, I know that probably SLI 980Ti would be a better (and easier) choice, but still – AMD needed.
Gaming PC with 3 (full HD/WQHD) or one 4k monitor. Should I go with Crossfire R390X (because of its 8 GB VRAM) or Crossfire R9 Fury X (because of better performance and HBM memory)?
Thanks!
